Task 11.41 - match none for aol
It seems that in some IOS versions (e.g. 12.4(15)T11) you may not be capable to configure "class-map type inspect" correctly as configured option does not stay in the running config - it's ignored.
# Example from SG:
class-map type inspect aol CMAP_AOL_NON_CHAT
match no service text-chat
Rack1R4#sh class-map type inspect aol
Class Map type inspect aol match-any CMAP_AOL_NON_CHAT (id 1)
The same issue has already been reported for CCIE SP materials - http://ieoc.com/forums/p/10167/104117.aspx
